SPECIFICATION forming part Of Patent No. 679,898, dated August 6, 1901.

' I Application filed February 25,1901. derial No. 48,746. (No model.)

To all whom it may concern:

Be it known that I, EMIL J ossa, residing at 158 Uhlandstrasse,Wilmersdorf, in the Kin gdom of Prussia, German Empire, have in-' ventedcertain new and useful Improvements in Means for SealingParts ofMachinery which have Reciprocating or Oscillating Motions, of which thefollowing is a specification.

This invention relates to an improved means or contrivance for packingor sealing parts of machines having reciprocating oscillating mo tionsor the like.

By means of this invention parts of machinery with reciprocating oroscillating motions are securely. packed or sealed against external orinternal pressure by connecting the movable part with an expanding ortelepscopic sheath or closed part and firmly conengine.

' 'necting the'expanding and contracting part with the part to be packedor sealed against external or internal pressure and combining theseparts withaconcealed outlet-chamber.

The" expanding and contracting elastic part, which resembles abellows inits action, may

be. made of difierent kinds of material (steel,

copper, india-rubber, or the like) and inva rious shapes or forms. Thissealing can further be employedin combination with any preferredpacking, and for the purpose of relieving the 'strainon the elasticpacking the The spindle a, having reciprocating motion or screws '5.

I is firmly. connected with the elasticor bellows 'part I), (beingsoldered thereto,) and the other 40 end of this bellows portion isconnected with the valve-casingd by means of a plate f,which is providedwith an annular recess g, which fits over an annular rib h on thecylinder-head. The plate f is held firmly in placeby a screw 5 Theelastic or bellows part may. act either as a sealing device jnrelationto 1 the vapor-inlet, or, as in the present case, for this purpose anyknown formof construction 4 maybe employed. The vapors escaping or 56leaking through this packing arrangement enter the concealed chamber a,which is conj tained' in the casing d beneath its top plate The vaporscan be carried 01f as desired through the passage e either into acondenser 5 5 v or into a vessel filled with a suitable fluid, in whichthey are absorbed, or they may be discharged into the atmosphere, wherethey are without-harmful efiect.

; What I claim, and desire to secure by Let-v 60 ters Patent, is-=- Thecombination of a cylinder, having a chamber 0 below its end wall 70, arod a pass:

ing through said chamber and said end'wall it, an outlet 6 from saidchamber, and the bellows 12 secured at one end to the rod, and clampedat. the other end to the outer side of the plate is, 1 v p In witnesswhereof I have hereunto signed, myname, this 8th day of February, 1901,in '70 the presence of two subscribing witnesses.
